This free online converter turns RM videos into M4V files in your browser, with no software to install and no watermark.

Otherwise the video is re-encoded as H.264 video with AAC audio.

What to expect from this conversion
- Expect a file of similar size to the RM original.
- RealMedia files are low-resolution by nature, so the result keeps the same detail level. Converting does not add detail.

- The first audio track is kept. Subtitle tracks, extra audio tracks and chapters are not included in the converted file.
